English champions United were made to work hard and defend resolutely at times in a nervy 1-0 win over Olympique Lyon at Old Trafford, courtesy of Cristiano Ronaldo’s 30th goal of the season in all competitions.

The winger pounced on a rebound from Anderson’s initial effort and threaded his shot past Gregory Coupet in the 41st minute as United equaled the record held by Juventus of 10 straight Champions League home wins.

United manager Alex Ferguson was pleased with the outcome that left his side on course to repeat the elusive 1999 treble although he acknowledged his troops struggled at times.

“We should have done more with the possession we had in the second half and we made it difficult for ourselves. But defensively we did well, they didn’t have any chances in the game,” he told ITV.
